Fold up playmat/toybox

Hi - not sure if this is the right topic for this but anyhow, I'm looking for a playmat that folds up into a toybox (well, two of them, one for each DC). We do have storage boxes in playroom but every day more toys seem to find their way into our living room and would like to just contain/hide them in the evening. Have seen the happy land one on ELC but want a bit bigger...anyone seen any?

Thanks - I saw those but ideally wanted something structured so that it doesn't mess up their toy "displays" - they spend hours arranging all their characters (in fact DD calls it Art) so I wanted to kind of leave in situ but not have to see them. Maybe I need a giant pop up tent and just stick it on top!
